Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038666, here are decompositions:

  • 23 + 1038643 = 1038666
  • 29 + 1038637 = 1038666
  • 37 + 1038629 = 1038666
  • 43 + 1038623 = 1038666
  • 47 + 1038619 = 1038666
  • 67 + 1038599 = 1038666
  • 103 + 1038563 = 1038666
  • 127 + 1038539 = 1038666

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 8666 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8666-03-01 (DMMYYYY (Euro, single-digit day))
  • 8666-10-03 (MMDYYYY (US, single-digit day))
  • 8666-03-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,038,666 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
